MongoDB\Driver\BulkWrite::__construct — Create a new BulkWrite

### Beschreibung

public MongoDB\Driver\BulkWrite::__construct(?array `$options` = `null`)

Constructs a new MongoDB\Driver\BulkWrite, which is a mutable object to which one or more write operations may be added. The write(s) may then be executed with MongoDB\Driver\Manager::executeBulkWrite().

### Parameter-Liste

`options` (array)

  options
  Option | Type | Description | Default
  --- | --- | --- | ---
  bypassDocumentValidation | bool | If `true`, allows insert and update operations to circumvent document level validation. This option is available in MongoDB 3.2+ and is ignored for older server versions, which do not support document level validation. | `false`
  comment | mixed | An arbitrary comment to help trace the operation through the database profiler, currentOp output, and logs. This option is available in MongoDB 4.4+ and will result in an exception at execution time if specified for an older server version.
  let | array|object | Die Zuordnung von Parameternamen und -werten. Die Werte müssen Konstanten oder geschlossene Ausdrücke sein, die nicht auf Dokumentfelder verweisen. Auf die Parameter kann dann als Variablen im Kontext eines aggregierten Ausdrucks zugegriffen werden (z. B. `$$var`). Diese Option ist ab MongoDB 5.0 verfügbar. Wenn sie für eine ältere Serverversion angegeben wird, kommt es bei der Ausführung zu einer Exception.
  ordered | bool | Ordered operations (`true`) are executed serially on the MongoDB server, while unordered operations (`false`) are sent to the server in an arbitrary order and may be executed in parallel. | `true`

### Fehler/Exceptions

- Wirft eine MongoDB\Driver\Exception\InvalidArgumentException, wenn beim Analysieren von Argumenten ein Fehler auftritt.

### Changelog

Version | Beschreibung
--- | ---
PECL mongodb 1.14.0 | Added the `"comment"` and `"let"` options.
PECL mongodb 1.1.0 | Added the `"bypassDocumentValidation"` option.

### Beispiele

Beispiel #1 MongoDB\Driver\BulkWrite::__construct() example

`<?php
$bulk = new MongoDB\Driver\BulkWrite(['ordered' => true]);
$bulk->delete([]);
$bulk->insert(['_id' => 1, 'x' => 1]);
$bulk->insert(['_id' => 2, 'x' => 2]);
$bulk->update(
['x' => 2],
['$set' => ['x' => 1]],
['limit' => 1, 'upsert' => false]
);
$bulk->delete(['x' => 1], ['limit' => 1]);
$bulk->update(
['_id' => 3],
['$set' => ['x' => 3]],
['limit' => 1, 'upsert' => true]
);
$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$writeConcern = new MongoDB\Driver\WriteConcern(1);
try {
$result = $manager->executeBulkWrite('db.collection', $bulk, ['writeConcern' => $writeConcern]);
} catch (MongoDB\Driver\Exception\BulkWriteException $e) {
$result = $e->getWriteResult();
// Check if the write concern could not be fulfilled
if ($writeConcernError = $result->getWriteConcernError()) {
printf("%s (%d): %s\n",
$writeConcernError->getMessage(),
$writeConcernError->getCode(),
var_export($writeConcernError->getInfo(), true)
);
}
// Check if any write operations did not complete at all
foreach ($result->getWriteErrors() as $writeError) {
printf("Operation#%d: %s (%d)\n",
$writeError->getIndex(),
$writeError->getMessage(),
$writeError->getCode()
);
}
} catch (MongoDB\Driver\Exception\Exception $e) {
printf("Other error: %s\n", $e->getMessage());
exit;
}
printf("Inserted %d document(s)\n", $result->getInsertedCount());
printf("Updated %d document(s)\n", $result->getModifiedCount());
printf("Upserted %d document(s)\n", $result->getUpsertedCount());
printf("Deleted %d document(s)\n", $result->getDeletedCount());
?>`

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    Inserted 2 document(s)
    Updated  1 document(s)
    Upserted 1 document(s)
    Deleted  1 document(s)
